OCV Series S65

Durable, Robust , High-pressure Resistant Control Valve

OCV S65 series is an automatic, hydraulically actuated, diaphragm operated, rigid seal, globe and angle pattern control valve. Featuring a robust design, resistance to high working pressure, flexibility in structural materials and resistance to extreme working conditions / environments, makes it a suitable safety valve for applications such as deluge, pressure control, water / foam and seawater fire protection systems. S65 valves consist of three major components: body, bonnet and internal diaphragm assembly.
